a company or factory code in the Monsters Inc. world. When an employee is contaminated with a foreign object of a human child, a 2319 goes into effect and alerts the Child Detection Agency (CDA). The CDA removes and destroys the foreign object, shaves and cleans the employee from any contamination and puts a cone around his head to protect himself from biting.

The number 2319 is also seen on car's license plate. It is also a reference to the Old Testament Exodus 23:19.

The sexual act of when making love to your significant other, right before one reaches climax. The male pulls out of their partner and ejaculates onto a sock. He then slaps the semen covered sock onto the partners back and proceeds to shout out "We've got a 2319, I repeat, we've got a 2319!"

Based on the monsters inc. reference, but used instead in real life when you see a goodarse on a female.

You're out in town with your mates and you clock a 9/10 arse but none of your mates have spotted it. In order to convey the message without suspicion arising from the girl herself or other members of the public the code 2319 is used.
